Abstract:

Objective

To compare the clinical efficacy of diclofenac sodium alone and in combination with the Chinese traditional medicine Fangfeng decoction in the treatment of knee osteoarthritis (KOA).

Methods

KOA patients were enrolled at Guanyun Traditional Chinese Medicine Hospital from January 2018 to January 2020. The patients were randomly divided into a control group (diclofenac sodium alone) or a combination group (diclofenac sodium+Fangfeng decoction). The incidence of adverse reactions, clinical response rate, visual analogue scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lysholm score were compared between the two groups.

Results

Finally, 180 patients were included, with 90 patients in each group. For patients with Kellen-Lawrence (K-L) grade Ⅲ disease, the combination group had a higher effective rate than the control group (100% vs 77.8%, P=0.045). For patients with K-L grade I/Ⅱ disease and those with K-L grade Ⅲ disease, the combination group had lower WOMAC scores (26.88±11.2 vs 38.16±12.8, P<0.001; 51.89±16.55 vs 70.83±16.37, P=0.001) and higher Lysholm scores (76.8±9.48 vs 66.95±13.26, P<0.001; 51.17±11.2 vs 42.61±10.44, P=0.013) than the control group. For patients with K-L grade Ⅳ disease, the combination group had a lower VAS score than the control group (4.47±1.68 vs 5.93±1.98, P=0.035).

Conclusion

Fangfeng decoction combined with diclofenac sodium has superior efficacy and safety in elderly patients with KOA. The combination treatment has more advantages in management of pain, stiffness, and joint dysfunction in patients with K-L grades I-Ⅲ disease, as well as relief pain in patients with K-L grade Ⅳ disease, which is worthy of clinical promotion and reference.
